BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates to a toolbox with reinforced structural strength and compression resistance.

[0003] 2. Description of the Related Art

[0004] The current toolbox models commonly use plastic injection and shaping for its production, of which the plastic injection and shaping is divided into hollow air-blow formation and solid formation. Please refer to FIGS. 1 and 2 for a prior-art toolbox A1, and its structure comprises an upper casing A2; a box body A3 having a recession for placing tools therein; and a latch section A4 disposed on the front end of the upper casing A2 for latching the box body. When the toolbox A1 is in use, it has the following shortcomings:

[0005] (1) Since general toolboxes are used to contain many tools, and the plastic forming toolbox under the pressure of a heavy load of containing tools may be lack of strength, unable to hold heavy load, and easily affected by external forces such as collision and has the shortcoming of destroying the toolbox.

[0006] (2) The material of the plastic forming toolbox is fragile, and the compression resistance for the loading is small, and thus having a shortcoming of a short life for the toolbox.

[0007] In view of these shortcomings of the prior-art plastic forming toolbox, the inventor of the present invention based on years of experience accumulated from the engagement in the related industry conducted extensive research to resolve the aforementioned shortcomings and invented the present invention.

SUMMARY OF THE INVENTION

[0008] The primary objective of the present invention is to provide a toolbox having a reinforced structural strength and compression resistance. To increase the structural strength and compression resistance of a toolbox, an upper casing in accordance with the present invention comprises a plastic layer with a reinforced structure and such reinforced structure enhances the strength and the effect of compression resistance of the toolbox.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0027] To make it easier for our examiner to understand the objective of the invention, its structure, innovative features, and performance, we use the following preferred embodiments together with the attached drawings for the detailed description of the invention.

[0028] Please refer to FIGS. 3 and 4 respectively for the perspective and cross-sectional diagrams of the assembled structure of the present invention.

[0029] In the figures, a toolbox 1 comprises an upper casing 2 and a box body 3; a recession disposed in the upper casing 2 and the box body 3 for placing tools; a latch section 4 disposed at the front end of the upper casing 2 for latching the box body 3, characterized in that a plastic layer 5 having a wrapped edge 6 is disposed on the upper casing 2 and the box body 3 for coating a reinforced structure 7, and such reinforced structure 7 has the effects of enhancing structural strength and improving compression resistance.

[0030] Please refer to FIGS. 5, 6, and 7 respectively for the perspective diagrams of the disassembled structure, assembled structure, and another assembled structure of the present invention.

[0031] In the design of another preferred embodiment of the present invention, the wrapped edge 6 of the upper casing 2 of the toolbox 1 includes a reinforced structure 7 which is secured by using a rivet 9 as shown in FIGS. 5 and 6, or both sides of the reinforced structure 7 are fixed by soldering as shown in FIG. 7, so that such reinforced structure 7 has the effects of enhancing the structural strength and improving the compression resistance.

[0032] Further, please refer to FIGS. 8, 9, 10 respectively for the perspective diagram of the assembled structure and the cross-sectional diagrams of the assembled structure, and another assembled structure of the present invention.

[0033] In the design of another preferred embodiment, a plastic layer with a reinforced structure is coated on an upper casing 2 of a toolbox 1 or a box body 3, and both ends of such reinforced structure 7 are rolled outward into a hook body 8 as shown in the cross-sectional diagram in FIG. 10, and the material of the reinforced structure 7 is iron sheet, aluminum sheet, stainless steel, or other hard material, so that the reinforced structure has the effect of enhancing structural strength and improving compression resistance.

[0034] Furthermore, please refer to FIGS. 11, 12, and 13 respectively for the perspective diagrams of the disassembled structure, assembled structure, and another assembled structure of the present invention.
